The Dems are in a very bad spot for 2012. BO won’t win because he is hated by everyone but blacks. If Hillary runs against him in the primaries or if he steps down and she (or anyone else) runs, the blacks will be angry and not vote.
That's why Zippo has to be forced out and make it look like the repubs did it.
Then Hillary gets to play the race card.
No they won’t, blacks as a whole are prcommitted to all Democrat nominees and will respond accordingly.
